The Lisbon Cathedral in Alfama was built in the 12th century. It is the oldest church in the city and has towers, gilded features, and a rose window that attracts many visitors. Admission to the church is free but a €2.50 fee is required to walk through the cloisters, which are open from 10AM to 5PM. Roman, Arabic, and Medieval structures are found in these ancient walkways, which may have once belonged to a mosque that existed where the cathedral now stands.

This edifice dates back to the first century B.C. and was discovered in the late 18th century. In addition to the amphitheatre, visitors can see columns and sculptures.

In the National Azulejo Museum, a visitor can see both colorful ceramic tiles and a beautiful Baroque-style chapel in one visit. The National Azulejo Museum is built within a 16th-century convent, in a remote part of the city tourists often miss. It is the only museum in Portugal dedicated to azulejos, ceramic tiles which hold significant meaning in Portuguese culture. Both convent and chapel on the site are historical buildings that were renovated after the earthquake in 1755.
